It's legal. If it doesn't do what you expect, check for leading, trailing or repeated internal spaces and consistency in using lower and upper case. Fix problems with -trim()-, -itrim()- and -lower()-.

I am trying to copy values of a string variable into another one if a

var 1                   var2
---------               ---------
jan-2000            jan-2000
march-2000       same year
june-1999          june-1999

replace var2=var1 if var2=="same year"

what is wrong with this code?
